Application led J'ulyvll, 1925. Serial No. 42,916.

flanges 6 are relatively narrow, butkare of` widths to contact with 'the upper surfaces of This inventionrelates to a device to be carried by the spring of a motor vehicle or the like, to supply the leaves of the spring with a lubricant Vat all times to enhance the rid-r ing qualities of lthe vehicle equipped with the spring.

Anotherl important object of the invention is to provide a device of this character which may be readily and easily removed and replaced so that repairs on the device or replacement of parts thereof may be carried out with facility.

A still further object of the inventionis to u provide a metal casing whichwill be water- 1" proof to eliminate any possibility of water finding its way to a point between the wiclr or felt lining of the device and the spring, to rust the spring.

l/Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that t' changes in the vprecise embodiment of the invention herein disclosed, may be made within the scope Vof what is claimed, without departing from the Spirit of the invention.

Referring to the drawing:

Figure l is a side elevational view of a spring equipped with lubricating devices constructed in accordance with the invention.

Figure 2 is a rlongitudinal sectionalv view ,N through a'spring boot or lubricating device.

m Figure 3 is a transverse` sectional view y through'the boot. y l Y Y Referring to the drawing in detail, the device includes a body portion indicated by the reference character 5 which is Vformed pref- L 'erably of sheet metal, the same being of a width slightly greater than the Width of the spring on which it is positioned so that the body portion may be held in position by means of its frictional contact with the wick ofthe 4device and the side edges of the spring.

Forming a lpart of the body portion are the end flanges 6, and lateral flanges 7 the lateral flanges 7 being of widths to extend ap- 59 preciable distances Aover the side edges of the spring to which the boot is applied. The end cated at 8 against movement longitudinally of the body portion. This wick is formed n preferably of felt and as shown by Figure 3 of the drawing, embraces the side edges and upper surface of the spring to carry the lu-l bricant to points between the leaves of the spring to lubricate them. l

voir that is supported bythe upper'surface of the boot or lubricator and has communication with the interior of the body portion 5 through the opening 10, which opening is closed by the wick 8 that receives oil by ab sorption therethrough.

The reservoir is provided with a filling opening l1 through which oil may be supplied to the reservoir. The securing device, forming a part of the invention is in the form of a rod 12 having eyes 13 at its ends, which eyes accommodate the lower ends of the coiled springs 14, the upper ends thereof being formed into hooks'l that pass into'y openings formed inthe body portion 5 as shown by Figure 3 of the drawing.

In use, the rod lf2,y is positioned under the the body portion arranged adjacent thereto, thereby clamping the body portion in position.

oil will beabsorbed by the felt ory wick 8,4

wick at each movement of the spring supporting the boot, with the result that the vehicle springs are thoroughly lubricated at all times.

I 'Claim IT*- A lubricator v springs, Vincluding a body portion of a width Y greater than the width of the spring to which `the body portion isv applied, `depending flanges formed at the sides and ends of the body portion, a wick held between the flanges, a rod having eyes at its ends lpositioned under the spring, spring members connected with the eyes, Said spring members having the spring and lio-ld the wick, which is indi- From the foregoing it will 'be obvious that n `6() The reference character 9 indicates `a reser- Y spring 'and the hook members 15 of the springs 14 are positioned'in the openings ofwhich oil will be squeezed from the felt or attachment for vehicle hooks at their upper ends, said hooks adapted to be positioned in openings formed in the bodyV portion, and reservoir on the body portion and adapted to i'eedoil to the Wick.

testimony that I claim the foregoing as my own, I have hereto affixed my signature.
